Why it has not any updated dependencies?

After finishing its related Udemy course, I archive this repository and unarchive it when I start a new training and add a link in the Other practice repos section referring to its new repo. But I don't update any associated dependency due to technology changes during the years between each practice, and the produced code which works with the mentioned requirements.

Requirements

• Node v16.13.2 or above
• A relational database (like PostgreSQL or MySQL, for example) (for 3-prisma)
• pgAdmin or any relational database client (for 3-prisma)

Repo structure

• 1-exercises: Exercises related to Andrew's course.
• 2-apollo: Server and Client projects from Apollo's Tutorial to understand an end to end implementation.
• 3-prisma: Prisma learning and integration with a GraphQL server.
• 4-testing: How to create and run unit tests for a GraphQL server

Setup

After cloning the repo, go to the created folder and install the node packages.

git clone https://github.com/NicolasOmar/graphql-practice.git
cd graphql-practice
npm run setup-all

setup-all is the command to install all the projects, but if you want to do it one by one, you can change that last line for one of the following:
